json.dump appears to add extraneous spaces before newline characters. By specifying the separators option, we can remove these whitespaces, reducing the diff noise.

object.entries 
An ES2017 spec-compliant Object.entries shim. Invoke its "shim" method to shim Object.entries if it is unavailable or noncompliant.
This package implements the es-shim API interface. It works in an ES3-supported environment and complies with the spec.
Most common usage:
var assert = require('assert');
var entries = require('object.entries');
var obj = { a: 1, b: 2, c: 3 };
var expected = [['a', 1], ['b', 2], ['c', 3]];
if (typeof Symbol === 'function' && typeof Symbol() === 'symbol') {
// for environments with Symbol support
var sym = Symbol();
obj[sym] = 4;
obj.d = sym;
expected.push(['d', sym]);
}
assert.deepEqual(entries(obj), expected);
if (!Object.entries) {
entries.shim();
}
assert.deepEqual(Object.entries(obj), expected);
Tests
